Hey try this guy
http://cgi.ebay.com/ebaymotors...7.m29 this guy has customer support that rivals Wes Stinson.
The software that he uses is "OBD1 Scan Tech" it scans the Engine, transmission, Airbag, AC and HICAS this software rivals if not is better than blazt.biz software called "Nissan Data Scan" (have not tested this yeat but seller says it to be true)
Tell him your from NICO and you might get it for $44 instead of $68.
You get it that cheap because you have to buy the serial cable-USB cable which runs from a couple of bucks to $40
